For

this purpose, the rotatable member of the cam era objective 8 is provided at a portion extending into the interior of the camera casing with a gear I 5 meshing simultaneously with two gears l6 and i1. Thegear it in turn meshes with the annular gear 3, while the gear ll meshes with a gear l8 which also meshes with the an-' nular gear a. It will thus be apparent that upon rotation rotatably adjusting or focusing the ob jective lens 8 the gear is will cause -a rotation of the annular gears 3, 4 or the pairbf rotary wedges simultaneously in opposite directio'n thereby effecting an finder simultaneously with the camera objective. I,

Heretofore it was customary to mount the prism bar forming the mirror base of the range focusing of the finder horizontally within the camera casing and with its longitudinal axis or sidefaces parallel with respect to the front and rear wall of the same. The present invention, however, contem- Plates 9. much better utilization of the space available within the camera casing and makes.-

it possible that not only the size of the casing can be reduced, but also that the operation of.

the range finder as far as the parallaxeflfect is concerned, is improved.

With particular reference to drawing be noted, that the prism bar I is mounted in an inclined position within the camera casing, not only with respect to a vertical plane but also with respectto ahorizontal plane. The

longitudinal side faces 20 and 2| (Fig.1 1) of the, prism bar I, which are parallel to-each other, are positioned at an angle with respect the front and rear wall of the camera casing, and also the parallel longitudinal top and bottom faces and 23 (Fig. 2) o! the prism bar I are positioned at an angle with respect tow the top and bottom wali oi the camera casing. The maximum inclination of the prism bar I with respect to the horizontal is limited by the conditions that upon arranging the raydefiecting means as close as possible to the camera objective 8 the bar I must remain just outside the beam of light passing through the camera objective, and that the opening which also serves as finder and is closed by the transparent glass plate 9 must remain completely unobstructed; What I claim as my invention is: i. In combination, a photographic camera having a camera casing provided withparallel front and rear walls and parallel top and bottom walls, a photographic objective on said front nail, and a range finder oi the mirror base type mounted within said camera casing, the front wail of said camera casing being provided with two laterally spaced openings located at difierent levels and on opposite sides of a vertical plane passing through the optical axis of said objective, said range finder including a prism bar forming the mirror-base of the range finder, said I prism bar being mounted just outside the beam adjustment of the range -;.objective, said range bar forming the mirror base of the range finder,
